Natural melatonin is a hormone produced in the pineal gland in the brain. It is made from the amino acid tryptophan and then released into the blood and cerebrospinal fluid, crossing into the brain. It sends messages to areas in the brain and body to help control the sleep and wake cycles...
Melatonin is a hormone secreted by the pineal gland, a tiny endocrine gland situated at the center of the brain.

Melatonin signaling and cell protection function.喜欢 0 阅读量: 21 摘要: Besides its well-known regulatory role on circadian rhythm, the pineal gland hormone melatonin has other biological functions and a distinct metabolism in various cell types and peripheral tissues. In different tissues and ...
Taken together, this study reveals the comprehensive transcripts and putative roles of melatonin synthesis genes as well as melatonin in immune responses in cassava. In 1958, N-acetyl-5-methoxytryptamine (melatonin) was first discovered in the pineal gland of cow, thereafter melatonin was widely ...
This review briefly summarizes the published data on relationships observed between melatonin - the main pineal hormone, and the thyroid gland. The prevailing part of the survey is devoted to thyroid growth processes and function. A large experimental evidence exists suggesting the inhibitory action of...
Melatonin is mainly an indoleamine hormone produced by the hypothalamic pineal gland of mammals. Its chemical component is N-acetyl-5-methoxytryptamine. In 1957, the dermatologists at Yale University separated and detected its molecular structure for the first time. Since then, melatonin has become ...
It is involved in the regulation of multiple functions, including the control of the gastrointestinal (GI) system under physiological and pathophysiological conditions. Since the gut contains at least 400 times more melatonin than the pineal gland, a review of the functional importance of melatonin ...
The function of melatonin, a hormone secreted by the pineal gland primarily at night, has not been definitively established in humans. To determine if pharmacologic doses of melatonin had any behavioral effects it was administered acutely to 14 healthy men. Their mood, performance, memory and visu...
Melatonin (MT) is secreted by the pineal gland and exhibits a striking circadian rhythm in its release. Depending on the species studied, some pituitary hormones also display marked circadian/seasonal patterns and rhythms of secretion. However, the precise relationship between MT and pituitary functio...
